Application tiled January 18, 1894:. v Serial No. 497,325. (No model.) v

To @ZZ whom it may concern:

13e it known that L-WILBUR P. SQUIER, a citizen of the United States,residing at Blair, 1n the county of Washington and State of Nebraska,have invented a new and useful Train-Order Signal, of which thefollowing is a specification.

My invention relates to improvements in railway train order signals inwhich a light with different 'colored glass is used'for night signalsand a colored signal board for day work; and the objects of myimprovement are, irst,-to provide such 'an apparatus in which all thesignalingfparts, shall both individually, and collectively, have anormaltendency to give the stopping or danger sign;second,-toprovideasignaluniversallyadaptable to differently locateddepots or signal stations; third,-to avoid the disastrous effects oftempestuous, freezing or windy weather; and, fourth,-to provide aneasily manipulated, simple, strong, durable, and positive acting signal,together with other important features more fully hereinafter set forth.I attain these objects with others of minor importancethrough the mediumof mechanism illustrated in the accompanying drawings, in which- UFigure 1, is a side elevation, partly in section portions being cut awayto show the assembly of the several parts, of the whole machine set upfor use.y Fig. 2, is a vertical cross section on the broken line X, Z,in Fig.'1, looking toward the signal board 3.- Fig. 3, 1s a top View ofthe rock-shaft 9 having the arms 33 and 33 carrying the colored lenses4and 4'; and Fig. 4, is an elevation ,of the operating wheel 16.

Similar numerals refer to similar parts throughout the several views.The horizontal tube 1, has one end seated against thewall 22, a post orother like perpendicular support, the opposite ends snugly inserted inthe thimbles 13 and 13 projecting centrally from opposite sidesand nearthe top of the lamp or lantern-case 28; an open clamping ring 14-havingthe tightening bolt 14 is placed on the thimble 13 to secure it rigidlyto the tube 1` andprevent turning or slipping; the top of the vring hasan eye by which to attach guy rods 15, to prevent lateral and verticalmotion of the extended end of the tube. The rock-shaft 2 is journaledcentrally through the tube, preferably in hardwood bearings 12, 12,'and12, the outer projecting end has the signal-board 3, rigidly attached byU shaped clamping bolts 27 and 27',

. the inner end .passes loosely through an aperture in the wall 22, andis provided with the operating wheel 16 rigidly attached thereto. Withinthe lantern case 28, the opening 6 is cut in the tube 1,-shown incross-section in Fig. 2,-and the rock-shaft has the stud or arm 5 so setas to oscillate in said opening, and limit the rocking of the shaft to aonefourth revolution,the signal board 3 being so adjusted on the shaftas Y to stop either in a horizontal plane as in Fig. 2, or a verticalplane as shown in Fig. 1; the operating wheel 16 has on its sideadjacent to the wall-22, the projections 23 and 23 and between these onthewall is set the stop .blockl 24 to limit the motionof the wheely to aone-fourth revolution agreeing with the motion ofthe shaft 2, the objectof which is to reinforce the stud 5 and prevent injury by theapplication of unnecessary force on the wheel, and make apositive stop,and as an alternative in case the stud 5 is broken or desired to beomitted. The rock-shaft 9, has its ends 9 and 9" pivoted in the bars 10and 10', and spans the case 28 at one side and at right angles to theshaft 2; near its ends the arms 33 and 33 project 'at right angles, andat the ends of the arms are the colored glass disks or lenses, set tonormally rest on the buffers 2l and 21 one at each side of the lamp 11between it and the sight openings or lenses of clear glass 17 and 17v inthe case 28, or to swing up to the posi` Vtion indicated by the brokenline in Fig. 1.

A bifurcated arm projects from the rock-shaft 9, forming theslot 29,between and parallel with the arms and directly beneath the opening 6 inthe tube `1; the eye-boltS is seated in this slot and adapted to'slidetherein and `be fastened at any point; the chain 7 has one end attachedin the eye of the eye-bolt, the other end passed up through the opening6 into the tube, over the shaft 2 to which it is attached by the pin 30;by changing 'the position of the eye-bolt iii-the slot, therange ofaction of the colored disks 4 and 4v isvaried and adjusted as desired.The wheel 16 is grooved on its periphery to receive the cord IOC 25,which is thereto attached; and a cleat 2G is attached to the wall onwhich to fasten the free end of the cord, when the signal board ishorizontal and colored disks raised.

To avoidthe turning of the signal board by the wind or storms it isconstructed with its axis of revolution corresponding, or nearly so,with its axis of symmetry. But, to insure 1t takingits position in aperpendicular plane when released by the operator or by accident to orfailure of other parts of the apparatus, its center of gravity is xed atone side or away from said axes. This is done in the construction shown,by the additional reinforcing bar 2O attached at one edge. The sameresult maybe reached by a board made of a single integral piecethickened at one edge. The projected end of the thimble 13 is madeconical, the shaft 2 passing loosely through an aperture at the apex,and this forming the chamber 18, around the shaft between the apex andthe adjacent hardwood bearing 12. At the base of the cone, on the underside the opening 19 is made, communicating with the chamber, to drainout any water that might be driven in around the shaft during storms.

The lantern or lamp 11,has a circularbase and is retained by lugs 31 and31 that pass through notches in the bottom of the case; further the lampis intended to be supplied with a globe and bail so that it may beremoved, cleaned, lighted and carried, being independent of the otherparts.

The tube 1 servesa double purpose of housing the rock-shaft 2 betweenthe operating wheel and lantern case, and with the collar 32 andsuitable guys, is a horizontal support for the whole apparatusprojecting at right angles to the road.

Inm operation when the cord 25 is released all the parts normally assumethe positions shown in Fig. 1, showing the broad surface of thesignal-board, and the colored glass disks, giving the danger or stopsign; the weight ot' the arms and disks, with the eccentrically placedWeight of the signal-board being sufficient to overcome all frictionalresistance; draft on the cord, turns the shaft 2 a onefourth revolution,bringing the signal board to a horizontal plane, the chain '7 winds upon the shaft and raises the colored disks showing a white light andindicating a clear track and no stop; the cord 'is then fastened tothecleat and retains the signals in this position.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A signal-board having ahorizontal axis of revolution correspondingwith its axis of symmetry, and parallel with its plane and its center ofgravity eccentric to Vsaid axes, to normally sustain the board in avertical plane substantially as described.

Il. In a signaling apparatus, a lantern case having oppositely disposedopenings with concentric projecting integral thimbles adapted to receivea horizontalsuppor'ting tube passed through the openings, a clampingring to fix one of the thimbles on the tube, the thimble adjacentto theend of the tubehavingacone shaped end with an opening at its apex toloosely receive a revoluble shaft journaled in and through the tube, andan opening at the lower edge of its base communicating with a chambersurrounding the shaft within the cone, substantially as described.

5.

6. In a signaling apparatus, a lantern case having a revoluble shaftprojecting therefrom in combination with a cone shaped projection on thecase to form a chamberaround the shaft, the cone having an opening atits apex to loosely receive the shaft, and an outer opening at its basecommunicating with the chamber, substantially as described.
